Hi, Martin
I am assuming you are complaining about limitiation of techniques derived
from ViewDependentShadowTechnique. If thats a such huge problem for you then
you may try to fix ViewDependentShadowTechnique to use RenderStage ptr
instead of CullVisitor ptr to index ViewDependentData. That requires some
bravery but I think there is huge chance it may be quite easy to do... Just
look at ViewDependentShadowTechnique / ViewDependentShadowTechnique.cpp and
see how CullVisitor pointer is used to recognize yet another view (slave) is
drawn and shadowed. Nested cameras use the same CullVisitor as parent cam
and thats the reason it does not work for nested cams, but RenderStages are
unique (I believe) so you may try to use current RenderStages obtained from
CullVisitior to index shadow instances....
I could help you with this, but not in this month... So have fun;-)
Cheers,
Wojtek

Subject: [osg-users] Problems with RTT, Shadowmaps and Callbacks
Hello,
I am so dissatisfied at the moment. I render my scene into a texture and put
it on a quad. I want use shadow maps in my scene, so I have to use a slave
camera, because shadowmap technique doesn't work with nested cameras. But my
problem is, all my callback function doesn't work now. The only work with
nested cameras. It is a big dilemma, isn't it? What can I do? Is there a
typical solution for this problem?
Thanks
Martin
